Read full description

Learn to write Japanese by hand: kanji, hiragana and katakana, with correct stroke order and instant feedback on every stroke. Kanji Write teaches you to write Japanese stroke by stroke: over 2,000 JLPT kanji plus all hiragana and katakana. Practice with your finger on iPhone or with Apple Pencil on iPad, and build real muscle memory. β—† Correct Stroke Order Every character is animated stroke by stroke and color-coded, so you learn the right order and direction from the start. No guessing, no bad habits. β—† Instant Feedback Each stroke you draw is checked against the correct shape and order. Miss a few times in Guided mode and a hint appears automatically. β—† Trace. Guide. Memorize. Three practice modes: trace over the character, follow the strokes one at a time, then write it from memory with the guides hidden. β—† Hiragana & Katakana All 46 basic kana in both scripts, plus the voiced forms (が, ぱ…). Search by romaji: type "ka" to find か and γ‚«. β—† Complete JLPT Library (N5–N1) Filter kanji by JLPT level, search by meaning or reading, and see on'yomi, kun'yomi and meanings for every character. β—† Built for Apple Pencil & iPad Pressure and tilt shape every stroke like a real brush. On iPad, practice in a notebook-style grid, like a calligraphy workbook. β—† Quick Sessions Tap play for a random set of characters from any level or script and review your results at the end.
